I checked your account, and what I see is:
- The URL https://alya-san.com does not work because the domain doesn’t have SSL yet. To fix that: How to get Free SSL (HTTPS) on InfinityFree
- The URL http://alya-san.com does work, and shows our default “Your domain is ready” page.
- The domain is setup as an Addon Domain, not a Parked Domain.
If you want to migrate the website of your existing free subdomain, you have two options:
- Move your website files from the location of your free subdomain to the location of your new domain. You can view the relevant directories in the Domains list in the client area, and you can move the files like this: How to move a website to a different directory
- You can remove the domain from your account and add it back. This time, make sure to add it as a Parked Domain or Alias of your free subdomain. That way, both your subdomain and your custom domain will show the same content.
